In contrast, Greater Adelaide saw employment rise by 4.2%, labour force grow by 3.9%, and unemployment fall to 3.5%. Jobs and Skills Australia's national employment forecasts from May-25 provide further insight into potential future demand within Mount Barker. These projections suggest national employment will expand by 6.6% over five years and 13.7% over ten years, with varying growth rates across industry sectors. Applying these projections to Mount Barker's employment mix indicates local employment should increase by 6.4% over five years and 13.4% over ten years, based on a simple weighting extrapolation for illustrative purposes.
